Final answer:
Manual coding is the best way to learn HTML because it provides a hands-on learning experience, deepens understanding of markup effects on function, and emphasizes attention to detail for error detection and resolution.
Step-by-step explanation:
Manual coding is considered the best way to learn HTML for several reasons. By typing out the code yourself, you gain a deeper understanding of the syntax and structure of HTML. This hands-on approach ensures that you learn how markup affects function by seeing the direct results of your code on the web page. Moreover, manual coding compels you to pay attention to detail, which is crucial for catching and fixing errors. In contrast with some WYSIWYG (what you see is what you get) editors where you might drag-and-drop content or apply styles similar to a word processor, manual coding offers no such shortcuts. This rigorous practice encourages you to learn the proper HTML and CSS codes, leading to a stronger foundation that will be beneficial for advanced web development tasks.
